You may make a left turn on a red light only from a:

1. One-way street onto a two-way street.
2. One-way street onto a one-way street. ✓
3. Two-way street onto a one-way street.

Answer: B. One-way street onto a one-way street.

You may turn left on a red light only when going from a one-way street onto another one-way street.

Why this is the answer

The handbook says a left turn against a red light is allowed when you are turning from a one-way street onto a one-way street. Before you go, check that no sign forbids the turn, and give the right-of-way to vehicles, pedestrians, and bicyclists who have a green light. Look both ways and turn only when it is safe. Turning from a two-way street or onto a two-way street does not meet this rule, which is why the one-way to one-way case is the only one listed that fits.

Why the other answers are wrong

• A. One-way street onto a two-way street. — Turning from a one-way street onto a two-way street is not the situation the handbook allows for a left turn on red.
• C. Two-way street onto a one-way street. — Starting from a two-way street does not qualify, since the handbook requires the street you leave to be one-way.

Remember it

Picture the rule as matching arrows: one-way in, one-way out, and the red left turn is allowed.
